However, this method requires a large number of screws to be installed for fixation, so that when disassembling, a large amount of time is required to remove the screws, consuming a lot of time and being unfavorable for the maintenance of the spark arrester. Summary of the Utility Model

[0005] The utility model provides a fixing device and a cooling type spark arrester to solve the problems put forward in the above background art.

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Embodiment 1:

[0027] As Figure 1 、 Figure 2 shown, this embodiment provides a fixing device for a cooling type spark arrester, including: fixing mechanisms 2 symmetrically arranged on the left and right sides of the spark arrester body 1 (that is, one fixing mechanism 2 is arranged on each of the left and right sides of the spark arrester body 1), first flanges 3 fixedly connected to the left and right sides of the spark arrester body 1 and the side of the fixing mechanism 2 close to the spark arrester body 1, and second flanges 4 fixedly connected to the side of the fixing mechanism 2 far from the spark arrester body 1;

[0028] And adjacent two first flanges 3 are connected by screws / bolts and other components, and heat insulation mechanisms 5 are fixedly sleeved on the inner sides of the two fixing mechanisms 2.

[0029] It should be noted that the spark arrester body 1 is a device for capturing and processing sparks in high-temperature flue gas. Its main purpose is to protect subsequent equipment such as dust collectors from damage by high-temperature sparks. The second flange 4 and the flange on the ventilation pipe are fixedly connected together by screws.

[0030] As Figure 3 , Figure 4 shown, specifically, the fixing mechanism 2 includes a first connecting cylinder 27 and a second connecting cylinder 28. One side of the second flange 4 close to the spark arrester body 1 is fixedly connected to one side of the first connecting cylinder 27 away from the second connecting cylinder 28. One side of the first flange 3 away from the spark arrester body 1 is fixedly connected to one side of the second connecting cylinder 28 away from the first connecting cylinder 27. The outer wall of the first connecting cylinder 27 is movably sleeved with a fixing sleeve 21. A first arc plate 22 is fixedly connected to the lower side of the first connecting cylinder 27 close to the second connecting cylinder 28. A second arc plate 23 is lapped on the outer walls of the first connecting cylinder 27 and the second connecting cylinder 28 near the upper side. And the first arc plate 22 and the second arc plate 23 are movably sleeved inside the fixing sleeve 21.

[0031] It should be noted that through the setting of the first arc plate 22, when the second arc plate 23 and the fixing sleeve 21 are removed from the outside of the second connecting cylinder 28, there is still a supporting component on the lower side of the spark arrester body 1, which is convenient for installing the spark arrester body 1 and prevents the problem that the lower side of the spark arrester body 1 has no component support during installation, resulting in difficult fixing due to the shaking of the spark arrester body 1.

[0032] As Figure 3 , Figure 4 shown, a plurality of annularly distributed limiting strips 24 are fixedly connected to the outer wall of the first connecting cylinder 27. The outer side of the limiting strip 24 is slidably connected in the inner chute of one wall of the fixing sleeve 21 away from the spark arrester body 1. Among them, the limiting strip 24 is used to limit the fixing sleeve 21 so that the fixing sleeve 21 cannot rotate on the outside of the first connecting cylinder 27.

[0033] As Figure 3 , Figure 4 shown, a plurality of annularly distributed hooks 25 are fixedly connected to the outer wall of the fixing sleeve 21, and a plurality of hooks 25 are evenly distributed horizontally. A plurality of annularly distributed quick-release buckles 26 are rotatably connected to the flange on the outer wall of the second connecting cylinder 28 close to the spark arrester body 1. The left side of the quick-release buckle 26 is lapped inside the hook 25.

[0034] The quick-release buckle 26 is a connection and disassembly technology widely used in many fields, especially in construction, automobile manufacturing and other industrial productions. When the side of the quick-release buckle 26 away from the spark arrester body 1 is lapped inside the hook 25, the fixing sleeve 21 is pulled and fixed towards the side close to the spark arrester body 1.

[0035] Example 2:

[0036] The difference between this embodiment and Embodiment 1 is only that, as Figure 4 shown, the outer surfaces of the first arc plate 22 and the second arc plate 23 are conical surfaces, and the sides of the first arc plate 22 and the second arc plate 23 away from the spark arrester body 1 are narrower.

[0037] The shapes of the first arc plate 22 and the second arc plate 23 are such that the closer the fixing sleeve 21 is to the spark arrester body 1, the firmer the fixing of the fixing mechanism 2 and the second arc plate 23 by the fixing sleeve 21.

[0038] Example 3:

[0039] The difference between this embodiment and Embodiment 1 or 2 is only that, as Figure 3 、 Figure 5 shown, the heat insulation mechanism 5 includes a first heat insulation cylinder 51, the outer side of the first heat insulation cylinder 51 is fixedly sleeved inside the first connection cylinder 27, and a second heat insulation cylinder 52 is fixedly sleeved inside the second connection cylinder 28.

[0040] The first heat insulation cylinder 51 and the second heat insulation cylinder 52 are used to isolate the first connection cylinder 27 and the second connection cylinder 28, so as to prevent the gas passing through from the inside from affecting the first connection cylinder 27 and the second connection cylinder 28 and causing the external devices to be deformed by heat.

[0041] Meanwhile, several annularly distributed springs 55 are fixedly connected to the surface of the second heat insulation cylinder 52 close to the spark arrester body 1. One side of the springs 55 away from the spark arrester body 1 is fixedly connected to a fixing ring 54, and one side of the fixing ring 54 away from the spark arrester body 1 is fixedly connected to a snap ring 53. The side of the snap ring 53 away from the spark arrester body 1 is movably sleeved in a groove opened on the side of the first heat insulation cylinder 51 close to the second connection cylinder 28.

[0042] The springs 55 push the snap ring 53 to make it abut against the inner side of the groove, so as to prevent the gas from passing through the gap between the first heat insulation cylinder 51 and the second heat insulation cylinder 52 and affecting the first connection cylinder 27 and the second connection cylinder 28.

[0043] Furthermore, two inner and outer snap rings 56 are fixedly connected to the position of the side of the fixing ring 54 away from the spark arrester body 1 close to the inner and outer edges. The outer sides of the snap rings 56 are movably sleeved in a ring groove opened on the surface of the second heat insulation cylinder 52 away from the spark arrester body 1. Thus, the gap between the fixing ring 54 and the second heat insulation cylinder 52 can be made more tortuous through the snap rings 56, reducing the influence of the internal substances on the springs 55.

[0044] Working principle of the utility model: First, when the second arc plate 23 and the fixing sleeve 21 are removed from the outside of the second connecting cylinder 28, the first arc plate 22 enables there to be a supporting component on the lower side of the spark arrester body 1, facilitating the installation of the spark arrester body 1 and preventing the problem that the lower side of the spark arrester body 1 has no component support during the installation, resulting in the difficulty of fixing the spark arrester body 1 due to its shaking. When the side of the quick-release buckle 26 away from the spark arrester body 1 is lapped inside the hook 25, the fixing sleeve 21 is pulled and fixed towards the side close to the spark arrester body 1. The shapes of the first arc plate 22 and the second arc plate 23 are such that the closer the fixing sleeve 21 is to the spark arrester body 1, the firmer the fixing of the fixing mechanism 2 and the second arc plate 23 by the fixing sleeve 21. The spark arrester body 1 and the fixing mechanism 2 are connected to the ventilation duct through the first flange 3 and the second flange 4.

[0045] When maintenance is required, directly remove the quick-release buckle 26 from the hook 25, and divide the fixing mechanism 2 into two parts, enabling the spark arrester body 1 to be quickly removed from the pipeline, facilitating the maintenance of the spark arrester. Finally, the first heat insulation cylinder 51 and the second heat insulation cylinder 52 are used to isolate the first connecting cylinder 27 and the second connecting cylinder 28, preventing the gas passing through the inside from affecting the first connecting cylinder 27 and the second connecting cylinder 28 and causing thermal deformation of external devices. The spring 55 pushes the snap ring 53 to make it press against the inside of the groove, preventing gas from passing through the gap between the first heat insulation cylinder 51 and the second heat insulation cylinder 52 and affecting the first connecting cylinder 27 and the second connecting cylinder 28. The function of the snap ring 56 makes the gap between the fixing ring 54 and the second heat insulation cylinder 52 more tortuous, reducing the influence of the internal components on the spring 55. Through the action of the first heat insulation cylinder 51 and the second heat insulation cylinder 52, the first connecting cylinder 27 and the second connecting cylinder 28 are protected on the outside, preventing the gas to be filtered passing through their inside from affecting external devices and causing thermal deformation of the outer components of the fixing mechanism 2 and affecting its service life.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the utility model.
